This is a fantastic episode because it shows almost true to form the nature of anti-fluoridationists - people who are opposed to fluoride based on junk science - and the ridiculous hurdles they create for communities because of the disinformation they provide. These folks are similar to the anti-vaccine people in that they read a few poorly conducted studies by people claiming something is bad and throw around terms they don't understand to incite fear and sway opinion. The thing that makes this episode especially fabulous is that the way they dramatized the situation is pretty close to how these situations play out in real life.
